RESUMEN
Objectives@#This study aimed to demonstrate the bone mineral density (BMD) and body composition in postmenopausal women with knee osteoarthritis (OA) who underwent surgical treatment, such as total knee arthroplasty, osteotomy, or meniscectomy. @*Methods@#A total of 254 women with OA aged 50 years who underwent surgical treatment were enrolled in this study. We evaluated obesity-related factors, muscle components, and BMD using dual-energy X-ray absorptiometry. @*Results@#No significant differences were noted in the BMD of the hip joint between the symptomatic side of the leg with knee OA and the contralateral side. However, when comparing the BMD of each component, the results indicated a significantly higher BMD in the obesity group based on body mass index (BMI). When defining sarcopenic obesity (SO) using various indicators of obesity (BMI, the estimated visceral adipose tissue area, android/gynoid ratio, and total body fat percentage), the prevalence of SO in the OA group who underwent surgical treatment ranged from 22.0% to 49.6%. @*Conclusions@#This study investigated obesity-related factors in patients with advanced knee OA who underwent surgery, revealing a high prevalence of overweight/obese individuals, the presence of SO, and a complex relationship between obesity, body composition, and bone density, highlighting the potential protective effects of weight-bearing on bone health while exploring the impact of sarcopenia on bone density differences in the context of OA. Depending on various definitions of obesity, diverse proportions of SO in patients with OA have been observed, and further detailed research is required to understand its impact on the condition.
RESUMEN
Fibromuscular dysplasia (FMD) of the renal artery is a non-atherosclerotic, non-inflammatory vascular disease that causes stenosis, aneurysm, dissection, and occlusion of the vessel. We report a rare case of a postpartum FMD patient who presented with spontaneous acute perirenal hematoma due to renal artery aneurysm rupture after cesarean section. The 40-year-old patient presented with sudden onset of abdominal pain 2 days after an elective cesarean section performed at full gestational term. A computed tomography scan of the abdomen revealed perirenal hematomas with signs of FMD in both renal arteries. The bleeding was successfully controlled by transcatheter arterial embolization. Short-term continuous renal replacement therapy was performed until her renal function recovered. FMD of the renal artery is rare in pregnant patients. Additionally, aneurysm rupture can be life threatening and requires immediate medical attention and prompt management.
